PIPE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 291,773, dated January 8, 1884.

(No model) To all whom it may concern Be it known that 1, ROBERT M. REILLY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a new and useful Improvement inPipe- Joints, of which the following is a specification. s

Figure 1 is a vertical elevation of my improved pipe-joiut, partly in section; and Fig. 2 is a horizontal section on line a a"- of Fig. 1.

My invention relates to improvements in pipe-joints; and it consists in the peculiar arrangement and construction of the parts, as hereinafter more fully described, and set forth in the claim.

In the accompanying drawings, a represents the male portion of the pipe, provided at its lower end with a ball, b, having an orifice, c, at its bottom for the passage of a fluid.

(Z and e are two collars formed on the lower end of the pipe a, just above the ball I), with a slight space between them.

h represents the female portion of the pipe,

the upper interior end of which is rounded out a t i to receive the ball Z2, which fits therein. The upper end of the female portion of the pipe h is provided with a flange, 7:, having openings Z for the passage of bolts.

m represents horseshoe-pieces, each provided over the center of its arch with a lug, n, having a hole, 0. The horseshoe-pieces m are inserted in the space between the collars d and c 011 the male portion a of the pipe, opposite each other, and are secured to the female portion h of the pipe by means of bolts 1), passing through the openings Z in the flange k, and thence through the holes 0 in the lugs n of the horseshoe-pieces m, whereby the male and female portions of the pipe are securely fastened together.

The advantage of forming the horseshoe connecting-pieces m separate from the male portion a of the pipe, instead of being rigidly secured thereto, is that the pipe and its 0011- nections have frequently to be turned to make 4 a branch pipe connect with another pipe, and when the male pipe is thus turned, if the horseshoe-pieces were rigidly attached to the male pipe, the holes therein would not register with the openings Z in the flange k, which objection is entirely obviated by'nlaking the horseshoe pieces on separate from the male portion of the pipe.

Another advantage of having the horseshoe-pieces separate from the male portion of 5 5 the pipe is that, when it is desired to give the male portion of the pipe a pitch or inclination, by tightening the nut onone side and loosening it on the other, it is easily done by means of the ball-andsocket connection between the pipes. If the horseshoe-pieces were rigidly secured to the male portion, the holes therein would not register with the holes in the flange It.

In some cases it may be found necessary to reverse the parts, placing the collars d e on the female portion of the pipe, and the flange It, with its opening Z, on the male portion of the pipe.

Having thus fully described my invention, 70 what I claim as new, and desire to secure by Letters Patent, is

The combination, with the male pipe a, provided with the ball Z2, having an orifice, c, in its bottom, and flanges d e, and female pipe 71, rounded out internally at its upper end, and provided with the flange it, having opening Z, of the horseshoe-pieces m, each provided with a lug, it, having a. hole, 0, and pins 10, substantially as described, and for the purpose set 80 forth.

ROBERT M. REILLY.
